You're going to have to get the National Dex, and then catch either a Sharpedo or a Carvanha. Sadly, the possibility of getting one is very low, so if you have a Pokemon with the move Thief, then you can see if the Carvanha/Sharpedo has one, instead of going through the trouble with catching them.
you have to have either a deepscale or a deepstooth you can get it by captn stern in slateport city but he trades you it you have to find a scanner which you finad in the abandon ship but you need the hm dive then when you either have a deepscale or a deepstooth give it to the clamperal and trade it .!!!!!!!! but deepening the item you get either a gorabess and a huntail deepscale : huntail deepstooth: gorabess hope this helps : = )
